FIREPRooF FLOORING.

SPECIFICATION forming part of Letters Patent N o. 682,683, datedSeptember 17, 1901. Y

Application filed November 2l, 1900. Serial No. 37,229. (No model.) v

T all whom it Wray concern:

Be it known that I, CHARLES F. HAGLIN, a citizen of the United States,residing at Min- 'neapolis, in the county of Hennepin and State ofMinnesota, have invented certain new and useful Improvements inFireproof Flooring `and I do hereby declare thefollowing to be a objectto improve that type of lireproof iioors wherein a skeleton of metal iscovered by a sheet or bodyof concrete; and to this end it consists ofthe novel devices and combinations of devices hereinafter described, anddefined in the claims.

The invention is illustrated in the accompauying drawings, wherein likecharacters indicate like parts throughout the several views. Figure 1 isa plan View, with some parts broken away, showing a portion of theiooring constructed in accordance with my invention. Fig. -2 is avertical section on the line m2 @c2 of Fig. 1. Fig. 3 is a detail Viewof a so-called tightening-link. Fig. 4 is a plan View corresponding toFig. l and illustrating a construction varying somewhat from that shownin Figs. 1 and 2, and Fig. 5 is a vertical section on the line m5 :v5 ofFig.' 4.

The numeral 1 indicates the horizontal and parallel v or approximatelyparallel floorbeams, preferably constructed of iron or steel, of theform known as I-beams. These beams are suitably supported at their endsand at other points, if desired, in any ordinary or suitable way. Inaccordance with my invention I perforate the web portions of the I-beams1 and pass through these perforations transversely of the beams a seriesof floor wires or rods 2. The wires 2 are in the best arrangementrigidly securedy to the webs of the beams 1, and this fastening is bestafforded by small wedges 3, which are driven through the perforations ofthe beams and against the said wires. The yokes or stirruplikebinding-wires 4 embrace the lower p0rtions of the beams 1, the upperends of the same being coiled around the overlying portions of the Wires2.

In the preferred construction (illustrated in Figs. 1, 2, and V3) twoHoor-wires 2 are passed through each perforation of a given beam 1, andthese wires are in the processr of able slack in the first place. Theyare then tightened by applying the links 5, which links preferably haveopen sides to the adjacent Wires, and then driving the said links towardthe beams l, so as to draw the floor-wires very taut. It is of courseevident that the links 5 may take various forms, but must, nevertheless,be in length less Athan the distance' between adjacent perforations inthe beams 1, so that they will draw up the floor- Wires as they areforced toward 'the secured portions thereof. These tightening-linksafford an extremely simple and efficient means for drawing thefloor-Wires taut, and they further increasethe strength of the structureby tying together the said floor wires transversely.

In the construction illustrated in Figs. 4 and 5 the Hoor-wires 2 areextended approximately parallel, and the tightening-links 5 not beingprovided said wires must be drawn taut by other means before they aresecured to the beams 1 by the wedges 3. B y means of thetightening-links the wires may be put under any desired tension. Inpractice the wires will be normally stretched, but to an extent lessthan their maximum coefficient of elasticity. When the cement hardensaround the wires, it adheres thereto.

The skeleton frameworks, formed by the beams and wires arranged yasabove indicated, are embedded in a heavy sheet or horizontally-extendedbody of concrete 6, having depending ridges 7, the latter of whichexembed the lower portions thereof and the yoke wires or stirrups 4. Theyoke-wires 4, while not absolutely necessary, are nevertheless verydesirable, as they reinforce and hold together the concrete ridges '7.It will of course be understood that the licor-Wires 2, which areembedded in the floor-forming body 5 of the concrete, will tie togetherthe said body and give the same the strength required to resist theloads to which it must be subjected. It will also ofcourse be understoodthat the size and number of the floorconstruction crossed and left withconsider-- ssl tend parallel with the beams 1 and serve to IOO wireswill depend upon the loads or strains which are to be put upon thefloor.

Vhile the above structure is especially designed for floors, it Will beunderstood that the same may be employed to form the Walls or partitionsof a building or the walls of various other structures.

i/Vhat I claim, and desire to secure by Letters Patent of the'UnitedStates, is as follows:

l. The combination with a series of metal beams', of a series of Wirespassed transversely through'the webs thereof, which wires are normallystretched, but to less than the maximum of their coefficient ofelasticity, and a sheet or body of concrete embedding the said stretchedwires, and adhering thereto, and strengthened thereby.

2. The combination with a series of beams, the series of Wires extendingtransversely of said beams, said wires being first set with a slack,sliding tightening devices serving to draw the said wires taut bysliding movements thereon, and a body or sheet of concrete embedding thesaid wires and tighteners, and strengthened thereby.

3. The combination with a series of metal beams 1, of the series ofwires 2 extended transversely through the webs of said beams, the ,keysor wedges 3 securing said wires to said beams, and the sheet or body ofcement 6 embedding said wires 2.

el. The combination with the metal beams I, of the series of wires orrods 2 passed transA versely through the Webs of said beams, theU-shaped wires or stirrups suspended from said wires 2, and embracingthe lower p0rtions of said beams, and the concrete floor sheet or body 6embedding said Wires 2 and the upper portionsof said beams, and providedwith the depending ridges embedding said yokes et and the lower portionsof said beams.

5. The combination with a series of beams, of a series of wires extendedtransversely through said beams, said wires being tirst set with slack,sliding tightening-links arranged to draw said Wires taut by movementstoward the said beams, and a body or sheet of concrete embedding thesaid wires and tighteners and portions of said beams.

6. The combination with a series of metal' beams, of a series of Wirespassed through said beams and crossed at their j unctions with saidbeams, said wires being first applied with slack, the tighteningrlinks 5Working on said Wires to draw the same taut, When driven toward thesecured or cross portions of said Wires, and a body or sheet of concreteembeddingthe said wires and strengthened and supported thereby.

In testimony whereof I aftix my signature in presence of two Witnesses.
